I'm getting the following error when trying to cmake a directory that has a CMakeList.txt and a file.cpp :

CMake Error at CMakeLists.txt:3 (find_package): By not providing "FindOpenCV.cmake" in CMAKE_MODULE_PATH this project has asked CMake to find a package configuration file provided by "OpenCV", but CMake did not find one.

Could not find a package configuration file provided by "OpenCV" with any of the following names:


Add the installation prefix of "OpenCV" to CMAKE_PREFIX_PATH or set "OpenCV_DIR" to a directory containing one of the above files. If "OpenCV" provides a separate development package or SDK, be sure it has been installed.

Any ideas? I've been looking around online, but can't find any concrete answers. Thanks!

I think your opencv path is not standard. Example in my install i have build opencv in opencv/build. Cmake cannot find opencv. in cmake gui I have got same error message and opencv is OpenCV_DIR-NOTFOUND

I have to set OPENCV_DIR to opencv/build
